His aim, in all his investigations, was the discovery and the defence of truth. - Jonathan Edwards

It does not answer the aim which God had in this institution, merely for men to have good commentaries and expositions on the Scripture, and other good books of divinity; because, although these may tend, as well as preaching, to give a good doctrinal or speculative understanding of the word of God, yet they have not an equal tendency to impress them on men's hearts and affections. God hath appointed a particular and lively application of his word, in the preaching of it, as a fit means to affect sinners with the importance of religion, their own misery, the necessity of a remedy, and the glory and sufficiency of a remedy provided; to stir up the pure minds of the saints, quicken their affections by often bringing the great things of religion in their remembrance, and setting them in their proper colours, though they know them, and have been fully instructed in them already.

Christians need constant reminders of how amazingly glorious our great God really is and what his glory means for our lives.

In things which concern men's worldly interest, their outward delights, their honor and reputation, and their natural relations, they have their desires eager, their appetites vehement, their love warm and affectionate, their zeal ardent; in these things their hearts are tender and sensible, easily moved, deeply impressed, much concerned, very sensibly affected, and greatly engaged; much depressed with grief at worldly losses, and highly raised with joy at worldly successes and prosperity. But how insensible and unmoved are most men, about the great things of another world! How dull are their affections! How heavy and hard their hearts in these matters! Here their love is cold, their desires languid, their zeal low, and their gratitude small. How they can sit and hear of the infinite height, and depth, and length, and breadth of the love of God in Christ Jesus, of his giving his infinitely dear Son, to be offered up a sacrifice for the sins of men, and of the unparalleled love of the innocent, and holy, and tender Lamb of God, manifested in his dying agonies, his bloody sweat, his loud and bitter cries, and bleeding heart, and all this for enemies, to redeem them from deserved, eternal burnings, and to bring to unspeakable and everlasting joy and glory; and yet be cold, and heavy, insensible, and regardless! Where are the exercises of our affections proper, if not here? What is it that does more require them? And what can be a fit occasion of their lively and vigorous exercise, if not such a one as this? Can anything be set in our view, greater and more important? Any thing more wonderful and surprising? Or more nearly concerning our interest? Can we suppose the wise Creator implanted such principles in the human nature as the affections, to be of use to us, and to be exercised on certain proper occasions, but to lie still on such an occasion as this? Can any Christian who believes the truth of these things, entertain such thoughts?
